Imagination is a core aspect of being human. Our imagination allows us to fully experience ourselves in relation to the world and reality. Imagination plays a key role in creativity and innovation.

Since the 17th century, however, imagination has been sidelined and dismissed as "make believe". Four centuries ago, a new way of knowing the world and ourselves emerged in the west and has gone on to dominate human life: science.

Imagination has been marginalized - depicted as a way of escaping reality, rather than coming to grips with it - and its significance to our humanity has been downplayed. Yet as we move further into the strange new world of the 21st century, the need to regain this lost knowledge seems more necessary that ever before.

This insightful and inspiring book argues that, for the sake of the future of our world, we must redress the balance. Through the work of Owen Barfield, Goethe, Henry Corbin, Kathleen Raine, and others, and ranging from the teachings of ancient mystics to the latest developments in neuroscience, The Lost Knowledge of the Imagination introduces the listener to a philosophy and tradition that restores imagination to its rightful place, and argues that it is not only essential to our knowing reality to the full, but to our very humanity itself.
